Trait Mapping 

pub trait Mapping {
    // Required method
    fn get_value(&self, key: &str) -> Option<&str>;
}

Abstracts concrete map types so that FromMapping could accept any of the implementors.

Required Methods

fn get_value(&self, key: &str) -> Option<&str>

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
